I'm also suggesting that there are lots of other options remaining that are not necessarily catastrophic. I'm not particularly optimistic about any of them, but I think I've come to the opposite conclusion to you: I think that wasting effort on global coordination is getting is closer to that catastrophe. Whereas even the other options that involve unthinkably extreme violence might at least have some non-zero chance of working.
I guess the irony of this reply is that I'm implying that I think _your_ position is naive. (Nuh-uh, you're the baby!) I suspect our main difference is that we have somehow formed very different beliefs about the likelihood of good/bad outcomes from different strategies.
But I want to be very clear on one thing: I am not an "anti-doomer". I think there is a very strong probability that we are completely boned, no matter what mitigation strategies we might attempt.
That's precisely what people have been saying about climate change. Some progress been made there, but if we can't solve that problem collectively (and we haven't been able to), we aren't going to be able to solve the "gain central control over AI" problem
